PROBLEM TO BE SOLVED: To improve workability when connecting pipe materials, in regard to the joint structure, a plug and a pipe joint for connecting pipe materials for supplying/discharging the fluid to/from equipment. SOLUTION: The pipe material 19 inserted into a connection hole 21 of the plug 20 is sealed by a rib 22 (a lock part also working as a seal part), while preventing a fall-off therefrom. Since the pipe material 19 is locked and sealed by using the elastic restoring force of the pipe material 19, a lock function and a seal function are shown by only inserting the pipe material 19 into the plug 20 fitted to the equipment 10. When connecting the pipe material 19, the work for rotating the pipe material with a tool for manual work such as a wrench in the condition that the pipe material is inserted is unnecessary, and workability is improved.
